Can also provide -d to specific the directory to store index files in,
-o to specific the location of your nodes file,
and -a for the names file.
Or the option -e to use the web-based entrez taxonomy database if you don't have the flatfiles installed.

This script requires that the bioperl-run pkg be also installed.

Providing the nodes.dmp and names.dmp files from the NCBI Taxonomy dump (see Bio::DB::Taxonomy::flatfile for more info) is only necessary on the first time running.
This will create the local indexes and may take quite a long time.
However once created,
these indexes will allow fast access for species to taxon id OR taxon id to species name lookups.
